ASCO 306-631 Rebuild Kit

The ASCO 306-631 Rebuild Kit is a critical maintenance solution for ASCO RedHat valve repair, specifically engineered for 8316 Series 3-way solenoid valves with a 1/4-inch NPT pipe size. This comprehensive solenoid valve rebuild kit includes high-grade NBR (Buna-N) elastomers, stainless steel springs, and a precision-machined core assembly to restore factory-spec sealing and cycle response. Designed for industrial fluid control, this kit ensures compatibility with air, water, and light oil applications where internal wear on the diaphragm or piston assembly compromises pressure holding. Replacing internal components with this ASCO valve parts kit prevents external leakage and erratic shifting, extending the service life of the ASCO 8316 G series pilot-operated valves. For contractors managing pneumatic systems or process control loops, utilizing genuine ASCO spare parts ensures that flow coefficients (Cv) and pressure ratings remain within original design tolerances, minimizing downtime during scheduled shutdowns.

• Optimized Sealing: High-performance NBR elastomers provide reliable shut-off and resistance to common industrial fluids.
• Direct OEM Fit: Specifically calibrated for the ASCO 8316 Series rebuild to maintain precise pilot-operated functionality.
• Complete Internal Restoration: Includes essential core, springs, and O-rings to eliminate common leak paths and mechanical sticking.
• Durable Construction: Stainless steel internal components resist corrosion and fatigue in high-cycle environments.

Is the ASCO 306-631 kit compatible with high-temperature steam applications?
No, this kit utilizes NBR seals. For high-temperature or steam service, a Viton or EPDM variant is required depending on the specific media and temperature range.

Does this rebuild kit include the solenoid coil?
No, the ASCO 306-631 contains internal mechanical components only. If the coil is burnt out or showing incorrect resistance, it must be purchased separately.

How can I confirm this kit fits my ASCO 8316 valve?
Verify the rebuild kit number on your valve nameplate. This kit is standard for the 1/4-inch 8316G054 and 8316G064 models using NBR construction.
